This inventionrelates to automatic lawn sprinklers, and more particularly to a sprinkler of the above nature adapted to produce an atomized rose spray for uniformly-distributing a stream of water from a hose over al large area of a lawn.

One object of the invention is to provide a lawn sprinkler of the above nature, in which the waterto be distributed is rst broken up by a rotating turbine, and then passed out of the sprinkler casing through' an apertured cap covering said turbine, whereby a spreading spray is produced.

A further object is to provide a lawn sprinkler of the above natur'e having im-' proved means for supporting it in raised position above the surface of the ground.

A further object is' to provide a lawn sprinkler ofthe above nature which may-be used alone or in series with other similar sprinkler units, the adjacent units being connected together by a plurality of yhose sections.

A further object is to provide a lawn sprinkler of the above nature which will be simple in construction, inexpensive tomanufacture, easy to install and manipulate, free from vibration, compact, ornamental in appearance, and very efli'cient and durable in use.

With these andother objects in view there have been illustrated on the accompanying drawings, five forms in which the invention may be conveniently embodied in practice.

In the drawings: Fig. 1 represents a perspective view'of the first form of lawn sprinkler embodying the invention as it appears in operating position supported above the ground with a hose noz'-` zle connected thereto. v v

Fig. 6 is an end iny Fig. 4. V Fig. v7 is a perspective ,view of aV fourth 'forni of the invention, having flat side wings for supporting the nozzle close to the ground. Fig. 8 is a longitudinal vsectional view of the same. n n Fig. 9 is a perspective view of one of the 'turbine members employed in each form of the invention.. y Fig. 10 is atop plan view of the sprinkler casing of the first form of the invention, with the turbine and cap removed to show'the interior construction.

Fig. 11 is a perspective view similar to Fig. 7 ofa fifth form Of the invention having open side wings constructed of heavy wire.

Referring now to the drawingsin which view-ofthe sprinkler shown i like reference numerals denote correspond- I ing parts throughout the several views, theV first form of lawn sprinkler shown in Figs. 1, 2, and 10, consists of a hollow spool-shaped cylindrical vertical casing 10 having an enlarged knurl'ed lower flange 11 and an'annular bead 12 at its upper-end. Extending inwardly from and integrally connected `to the bead 12 'is a flat annular section 13 having Va depressed central inverted dome 14 formed therein, said dome being provided with a plurality of angular depressionsf15,

lower end bent tightly about the bead 12 at the top of the casing 10. Within the'space between the dome 14 and top section.` 18 of the cap member 17, a turbine disc 23 is mounted. AsV most clearly shown in Fig. 9, .said turbine disc is provided with a plurality of flat radial sections 24:, five in this instance, separated by an equal number of ioo i through; an aperture at the VAbottom yof vthe dome 14 and headed overrat28 under the lower wall thereof.V The diameter of the 23vis slightly lessthantliat ofthe upper .part of the dome 14,V as shown inFig. 2. Y

The upper end of the spindle 27 kis` provided with a flange 29 for limitingthe upward movement of the Aturbine disc 23 under the pressure of the water passing through the sprinkler.

4The. interiorv wall .30 ofthe cylindrical portion of the casing is threadedto receive a standard nozzle 31 of a. garden hose 32, as shown in dotted lines in The end of said nozzle 31 is adapted -to'engage against a rubber washer-'33 of rectangularA cross-section vfor producinga water-.tight In orderito'support the sprinkler atan elevated position labovejthe lawn, provision is made of a vertical `ground-engaging rod 34 having a pointed lower extremity 35 and a horizontal upper section 36, saidupper'section including aresilientl clip 37 adapted tol fit snugly and detachably around the casing i l p connected together by hose sections, each of which has a nozzle 31 on one end 10 between the flanges 11 and 12 thereof.

" Operation" j l In the operation of the vfirst formv of the invention, the water'from the hose 32, in

passing upwardly throughthe slits 16l of the depressions 15, will impinge against-the turbine discv 23 and Vbe deflected outwardly intothe space 22. The water will then move inwardly andpass upwardly out of the nozzle through the central aperture 19, emerging from the sprinkler in an interrupted stream vof finely divided Yatomized drops of water,

which will spread outwardly over a. wide area due tothe rotative energy Stored up therein. 1 1 l The vmodified form of sprinkler shownin Figs. 3,4and 6 comprises a horizontal' shell 38,ha-v-ingone Yend 39 closed and the other end 40 threaded for receiving a coupling 41 fastened tothe end of a hose 42, as shown `in Fig. 3. The shell 38- is seatedin a curved metal strip section 43 to which it is connected, as byy a rivet 4,4. The curved section 43 is formedintegral -with a downwardly, eX-

tending strip 45 secured to the top of a-wooden ground-engaging post 46, as by 'a pair of screws 47.l v

y The top of the shell38 is provided.. with an inverted dome 48 similar in allrespects to the dome 14 shownin ythe firstform ofthe invention'. Thus, the dome 48 is perforated at three points 49, as before, to permit the'passage of Water upwardly vtherethrouglfiV for rotating a turbine disc 50'identical withthe turbine 23 Vpreviously described. The turbine disc 50 is covered bya flat cap member 51 having a central circular aperture 52 as before, and said cap member'51 has ak pair of curved flanges 53 shaped to fit about the cylindrical surface'of the` shell 38, to which surface they are secured as by soldering.

,4 When the second form of sprinkler, illustrated in Figs. 3, 4 and 6, is connected with the hose 42 and the water is turned on, the

spreading spray or mistlwhich emerges from the aperture 52 will besimilar in allrespects to' the'spray formed by the sprinkler shown Y in Figs. 1 and v2.

l The third form of'lawn sprinklershown in Fig. 5 is identical in all respects with the sec- Yondform shown Vin Figs. .3, 4 and 6, except .that instead .of having a shell with a closed end,.a shell 53 is provided having two open 4ends 5.4.andv 55, both of which are threaded.

The end 54is'enlarged for receiving the nozing lemployed to Vprevent leakage. The end 5 5 isadapted to-.receive the couplingf41 of a `hose 42 when it is desired to'connect the sprinf ated from onesource of water supply and-9is pling 41 on theother end. f Y

It will also be understood, that when it is vdesired to use this third yform of vshell 53 as a terminal sprinkler, it will merelybene'cessary to `screw a threaded cap 57 having a knurled bead on its outer end over the threaded end/55offsaid shell V53, a washer 58v being preferably provided within said cap 57 toV form a water-tight sealtherein. j g .In the; fourth form of theinvention shown in Figs. 7 and 8, the sprinklergcomprises a shell l59, identical in all respects with that of the third form, shown in Fig. 5, except for the ,construction of the dome 63 and the lcap 60,'which in'thisV instance has a pair of downi Wardly-extending flared curved Wing sections n 61 for supporting the shell 59y lclose tothe ground, said wings 61- being provided with curved ribs 62 adjacent their peripheries for strengthening purposes. v The cap GOmay be secured to the shell 59m any desired manner,

as bysoldering v The shell 59 is provided with a. dome 63 which is made separately therefrom, and has `an annular iange 64 adapted to lit vWithin a anda coules Y .los Y constructed of heavy wire and secured as by soldering to the underside of said shell 66.

One advantage of the four last illustrated forms of the invention is that the sprinklers may be located closer to the ground than was possible with the iirst form of the invention.

This is due to the fact that the hose nozzle 31 and coupling 41 may be held in horizontal positions when screwed upon the threaded ends of the shells.

Another advantage of the present invention is that practically all parts of the sprinkler can be readily made at a relatively lovs7 cost from sheet metal in automatic stamping presses and screw machines.

IVhile there have been disclosed yin this specification ive forms in which the invention may be embodied, it is tobe understood that these forms are shown for the purpose of illustration only, and that the invention Yis not to be limited to the speciiic disclosures, but may be modified and embodied in various other forms without departing from its spirit.

In short, the invention includes all the modin lications and embodiments coming within the scope of the following claims.
